YS3 PC-E BGMs are one masterpiece and the best one I ever heard. All musical instruments produced by LA/FM (Linear Arithmetic / Frequency Modulation) synthesis. Hudson sound engineering team did a really miracle on YS3, 米光亮 also composed an unique arranged BGMs on PC-E. I just can say, PCE-YS3 sound quality are perfect, no BGM could did this milestone ever, especially those musical instruments of LA/FM synth (crystal clear).... could not be re-birthed by software synth any more, it must be pure hardware synth.
